What happened?
The list of transactions (payments/receipts) to be selected for reversal contains items which already have been reversed or which are reversing another transaction. This makes it hard to select the right transaction in case of multiple reversals and reposts.
What should have happened?
Payments/receipts which have already been reversed (or are themselves reversing) need to be excluded from the list of transactions that are eligible for reversal.
